To evaluate supplied product for all purpose soil removal from steel and VCT surfaces.
Pre-weighed painted steel, painted VCT coupons were soiled with one gram of DCC 17 soil (33% vegetable shortening, 33% lard, 33% vegetable oil, 1% carbon lampblack). The coupons dried for 24 hours at room temperature (68 F) before recording the dirty weights. Three coupons of the same substrate were placed onto the Gardner Straight Line Washability unit. A Wypall X60 reinforced wipe was attached to the cleaning sled and soaked with one spray of the cleaner. The supplied cleaner was diluted with one pack to 5 gallons of room temperature tap water, and the comparative cleaner was used at the supplied dilution. Each coupon was then sprayed once with the same cleaner. The cleaner penetrated for 30 seconds before cleaning in the SLW unit for 20 cycles (~40 seconds). Clean coupons were air dried at room temperature (68 F) overnight before recording final weights.
